Drove out to Vegas for N2, have a ticket for L.A. N2, and will buy one for N1, but Only if there is a ticket price drop, which still hasn't occurred.
Taking a vacation back east in June, and could alter my itinerary a bit to be in Philly for N2. Given the lack of any real difference in the setlists so far, I'm probably not going to bother. Obviously U2 is being pretty upfront about the fact the songs are going to remain 95%+ the same for every show on the tour, and while it would be great to see them again, it would not be $100+ great. The ticket prices are just too high to justify paying them multiple times, for essentially the same experience, and one which if I really wanted to, I could also follow to a certain extent on Periscope over the next few months.
Would not be surprised to see more empty seats in the lesser markets as the tour continues, since without people traveling to cities outside their own, these venues will have a hard time selling out to locals willing to pay the high ticket prices, which pretty much top off at $330+ in every market, big or small.
